JUMPER CABLE-TAP.

Patented Dec. is, raw.

Application filed June '19, 1911. Serial No. 633,985.

In describing this invention reference is had to the accompanying drawing .in which like characters designate corresponding Figure 1 is an elevation of this cable tap, the sleeve of insulation being shown in section and the contiguous portions'of the con-. ductors being also shown.

Fig. 2 is a sectional view of parts seen in Fig. 1, the movable jaw thereof being shown as in its open position.

Fig. 3 is an elevation of the detached body of this cable tap.

" Fig. 4 is a detail view of the movablej aw trating the manner of attaching the same to a conductor. I

This cable tap comprises, generally, a a fixed .j aw carried by the body, and a spring pressed jaw movable toward and mental .bore at the lower said sleeve being forced 7 threading on the lower end of the turned shoulder-8 abuttmg against the lower from the fixed jaw.

1 is the body having'means at one end for coupling a conductor jaw 3 at its other end by means of which detachable connection is made with another conductor 4. The fixed'jaw 3 is hook shaped.

The means for coupling the conductor 2 may be of any desirable form, size and constructi'on and as here shown comprises an expansible and contractile sleeve 5 whlch is fitted ,on the' stripped end 6 of a cable or condu'ctor, the sleeve having a conical peich fits into a compleend of the body 1, into such bore by ripheralsurface Wh means of a sleeve nut body 1 and having an in-v end of the. sleeve 5 9 is a movable aw for coactmg with the .fixed jaw 3 and holding the conductor 4, the

interposed between the ion and highly o'f the operator- 2 thereto and a fixed jaw 9 being carried by a sleeve 10 encircling the body 1 and having an internal shoulder 11 opposed to an abutment or shoulder 12 threading on the lower end portion of the body 1. The sleeve constitutes a depending handle for the movable jaw. 1

13 is a spring encircling the body 1 and shoulders '11 and 12 and operating to move the sleeve axially of the body 1 to carry the jaw 9 toward the fixed jaw 3. The jaw 9 and sleeve 10 are oonronn'rion or new held from turning about the body 1 by any a suitable means as a screw 14:, extending through an opening 15 in the jaw and into a lengthwise peripheral slot 16 in the body 1.

17 is a sleeve of insulation encircling the body 1 and coupling carried thereby, the sleeve 17 being fixed to the sleeve lOand serving as a handle by means of which the sleeve 10 and jaw 9 can be moved away from the fixedjaw 3 against spring'13, said sleeve having a guard flange 18 at-its upper end for preventing the handfrom engaging with any live parts of the tap.

used in mines or other places where it 1s necessary to tap feed wires at various points, 3

and in operation the workman grasps the sleeve 17 and slides the same downwardly axially of the body 1 opening the jaw 9 permittingthe fixed jaw '3'to be hooked over the feed wire; The sleeve is then released and the spring 13 presses the jaw 9 toward th fixed jaw 3 and causes the jaw 9 and fixed jaw 3 to tightly clamp and make a good contact with the conductor- What we claim is:

1. A cable tap comprising a body having means for connection with an electric wire, and a pair of jaws, one of which is hookthe action of the shaped and is rigid with the body and the other of which is movable relatively to the body toward and from the former jaw, the movable jaw having a depending handle extending lengthwise of the body, and a spring for forcing the movable j aw toward the fixed jaw, substantially as and for the purpose I described. o

2. A cable-tap comprising a body having a shank, a fixed jaw at one end of the shank arranged to project beyond and overhang the side lines of the shank, a movable jaw having a portion mounted on and slidable along the shank, the latter jaw being mov- 80 Our tap is particularly applicable to be able at one side of the shank toward and from. the fired jaw, means connecting the movable jaw and the shank to prevent movement of said jaw about the shank, and a spring encircling the shank and acting on the movable jaw to move the same toward the fixed jaw, substantially as and for the purpose described. a

3. A cable tap comprising a body having a shank portion threaded near one end, and a jaw carried by the shank portion, a nut threading on the shank portion and forming a peripheralshoulder thereon, a jaw movable lengthwise o]? the shank portion toward and from the former jaw for clamping and making electrical contact with a conductor, means supporting the movable jaw and encircling the shank portion and slidable along the same, and having a sur face opposedto said nut, and a spring interposed between the nut and said surface, substantially as and for the purpose described. v

l. A cable tap comprising a body in the former a shank, and a jaw-carried at one end of the shank, the shank being threaded at its other end and having a nut threading thereon and fornding a peripherals'houlder,

shank, a jaw slidable lengthwise of the shank toward the former jaw for clamping embracing the shank and slidable along the same, and a spring interposed between the last-mentioned means and said shoulder, gulstantially as and for the purpose speci- 1e 5. A cable tap comprising a body formed with a jaw, a jaw movable lengthwise of the body toward and from the former jaw, a spring for moving the movable jaw toward the former jaw and thereby clamping and making electrical contact with a conductor, and a sleeve of insulation encircling the shank and the spring and being connected to said jaw, said sleeve having a flange ad-- jacent the movable jaw, substantially as and for the purpose described.

. In testimony whereof, we have hereunto signed our names in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 15th day of June, .1911.
